摘要： PROBLEM TO BE SOLVED: To materialize a beam rotator that makes an irradiation angle of a laser beam variable relative to a workpiece without accompanying reciprocating movement of a wedge prism. SOLUTION: A laser beam L13 that passed through a third and a fourth wedge prism 30, 38 of an angle rotator 14 goes through a second reflection mirror 52a to a fourth reflection mirror 52c and is made incident again on the fourth and the third wedge prism 38, 30 in an inverted state. Therefore, by rotating at least one of the two wedge prisms in a prescribed direction and by adjusting phase difference between the two, the optical axis of the laser beam L14 emitted to a radial rotator 12 can be parallel-translated with a prescribed width.

摘要： PROBLEM TO BE SOLVED: To provide technique by which a temperature range which is the standard of deciding whether the quality of working is good or bad can be calculated about every object of working.
SOLUTION: The method of laser beam working is provided with: a process where a laser beam for reference is emitted on a surface of the object 38 of working; a process where the intensity of the beam which is reflected by the surface is detected with the reflected intensity sensor; a process where the transmissivity or the rate of absorption of the object 38 of working is calculated on the basis of the output; a process where allowable temperature range to be the standard for deciding the quality of working is calculated on the basis of this transmissivity or the like; a process where a laser beam for working is emitted onto the surface of the object 38 of working; a process where an infrared ray having a prescribed wavelength which is radiated from the object 38 of working is detected with a first infrared sensor; a process where an infrared ray having a different wavelength from the above wavelength which is radiated from the object 38 of working is detected with a second infrared sensor; a process where the temperature of the object of working is calculated on the basis of the output from both infrared sensors; and a process where the output of the laser beam for working is adjusted when the temperature of the object 38 of working is deviated from the allowable temperature range.
